(Relevant code only. No input or output required. Assume that The list of integers is terminated by a zero word (not part of the list) R6 locates the start of the block

Explanation / Answer

0110 010 010 000000

0110 001 001 000000

R6 locates from start of the blocks , then first of the integers termineted by the zero words
